Not delivering to Gmail address error message not being able to authenticate mac.com address

I have a test email address on GMail. Suddenly on July 3 I get my emails sent to my spam box with this error message

 

This message has a from address in mac.com but has failed mac.com's required tests for authentication. 

 

WHAT'S UP!!!  I also noticed that our email open rate dropped almost by half in the same time. HOW DO WE FIX THIS???????????????????

Hi @JohnF39

 

Thanks for joining us in the Community. We can certainly understand why it would be helpful to test emails from your mac.com email. This is something our engineers are currently looking into. Your account has been set to be notified with updates. In the meantime, you are welcome to use an additional email address other than Mac/ICloud/Me. 

 

Also, we did see your other post on open rates and have responded. For reference, our reply is here
